I can't think of any reason why a better faster processor on machines with six or more dimensions of freedom (X, Y, Z, Extrusion or cutting rate, Time, Temperature at the bare minimum) would not benefit from a more capable processor, so the basic idea of using an STM32FXXX is sound. Adding more vari...

If you get the right supplier, then in theory you can build it for the same or less than the cost price (as opposed to the approx $20 retail price) of those melzi clones. If we assume the cheap Melzi clone is making someone between 20 and 50%, then back of a fag packet calculations suggests build co...

Also worth bearing in mind is the bottom line. What could you realistically expect to make per board. You are competing against the likes of the cheap $25 Melzi clones for peoples attention. You either need to beat them on price, or add some extra magic to stand out from the crowd. Faster, more accu...

Once upon a time a long time ago, I discovered norton antivirus Windows to be so intrusive that I'd consider it as almost a virus.
Subsequently I decided I'd treat it as such,usually a full re-install I replace it with Linux.
